[texts]Reducing/Eliminating ESD Hazards During Pyro Operations - Soriano, Jose Francisc
Several safety concerns have occurred during pyro operations at 30% or lower RH in the OPF area based on the increase of electrostatic discharge (ESD). These concerns targeted the safety of personnel, flight hardware, and ground support equipment (GSE). Two proposed methods considered to control ESDs during pyro operations at 30% or lower RH are the use of an ionizer blower and to increase the moisture content...

[texts]GRO source candidates: (A) Nearby modest-size molecular clouds; (B) Pulsar with Wolf-Rayet companion that has lost its H-envelope - Silberberg, R.
Within 100 pc of the sun there are over a hundred cirrus clouds with masses of approx. 60 solar mass and dense molecular clouds with masses of approx. 4 solar mass. If the local interstellar density of cosmic rays is also present in these clouds, the flux of neutral pion from the decay of gamma rays from the core of a cloud at a distance of 20 pc is approx. 13 x 10(exp -8) photons/sq cm/s. The flux from the more extensive cirrus cloud is approx 4 x 10(exp -7) photons/sq cm/s...

[texts]Measured and calculated acoustic attenuation rates of tuned resonator arrays for two surface impedance distribution models with flow - Parrott, Tony L.
An experiment was performed to validate two analytical models for predicting low frequency attenuation of duct liner configurations built from an array of seven resonators that could be individually tuned via adjustable cavity depths. These analytical models had previously been developed for high frequency aero-engine inlet duct liner design. In the low frequency application, the liner surface impedance distribution is unavoidably spatially varying by virtue of available fabrication techniques...

[texts]Uncertainty Analysis for Fluid Mechanics with Applications - Walters, Robert W.
This paper reviews uncertainty analysis methods and their application to fundamental problems in fluid dynamics. Probabilitic (Monte-Carlo, moment methods, polynomial chaos) and non-probabilistic methods (interval analysis, propagation of error using sensitivity derivatives) are described and implemented. Results are presented for a model convection equation with a source term, a model non-linear convection-diffusion equation: supersonic flow over wedges expansion corners, and an airfoil; and tw...

[movies]Bright Fireball Over Georgia
A camera in Cartersville, Ga., captured this view of a bright fireball over Georgia on the night of Mar. 7, 2012, at approx. 10:19:11 EST. The meteor was first recorded at an altitude of 51.5 miles (89.2 km) southeast of Tunnel Hill, Ga., moving slightly south of west at approximately 15 km/s (33,500 mph). It was last seen 16.9 miles (27.2 km) above State Road 95, southeast of Rock Springs, Ga. (NASA/MSFC/Meteoroid Environment Office)

[texts]Uncertainty in Computational Aerodynamics - Luckring, J. M.
An approach is presented to treat computational aerodynamics as a process, subject to the fundamental quality assurance principles of process control and process improvement. We consider several aspects affecting uncertainty for the computational aerodynamic process and present a set of stages to determine the level of management required to meet risk assumptions desired by the customer of the predictions.

[texts]Microcomputer based controller for the Langley 0.3-meter Transonic Cryogenic Tunnel - Balakrishna, S.
Flow control of the Langley 0.3-meter Transonic Cryogenic Tunnel (TCT) is a multivariable nonlinear control problem. Globally stable control laws were generated to hold tunnel conditions in the presence of geometrical disturbances in the test section and precisely control the tunnel states for small and large set point changes. The control laws are mechanized as four inner control loops for tunnel pressure, temperature, fan speed, and liquid nitrogen supply pressure, and two outer loops for Mach...
